Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Pro Graphics and the GeForce GT 740M are equal.
The GeForce GT 740M has a 610 MHz higher core clock speed and 24 more Texture Mapping Units than the Pro Graphics. This results in the GeForce GT 740M providing 24.3 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.
The GeForce GT 740M has a 610 MHz higher core clock speed and 14 more Render Output Units than the Pro Graphics. This results in the GeForce GT 740M providing 12.6 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
The Pro Graphics was released less than a year after the GeForce GT 740M, and so they are likely to have similar driver support for optimizing performance when running the latest games.
The GeForce GT 740M has 1920 MB more video memory than the Pro Graphics, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GT 740M also has superior memory performance overall.
The GeForce GT 740M has 16 GB/sec greater memory bandwidth than the Pro Graphics, which means that the memory performance of the GeForce GT 740M is slightly better than the Pro Graphics.
The Iris Pro Graphics 5200 Mobile has 40 Shader Processing Units and the GeForce GT 740M has 384. However, the actual shader performance of the Pro Graphics is 208 and the actual shader performance of the GeForce GT 740M is 311. The GeForce GT 740M having 103 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 740M delivers a noticeably smoother and more efficient experience when processing graphical data than the Pro Graphics.
The Pro Graphics transistor size technology is 6 nm (nanometers) smaller than the GeForce GT 740M. This means that the Pro Graphics is expected to run very slightly cooler and achieve higher clock frequencies than the GeForce GT 740M. While they exhibit similar graphical performance, the Pro Graphics should consume less power than the GeForce GT 740M.
The Iris Pro Graphics 5200 Mobile requires 47 Watts to run and the GeForce GT 740M requires 45 Watts. The Pro Graphics requires 2 Watts more than the GeForce GT 740M to run. The difference is not significant enough for the Pro Graphics to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 740M.
|Mini Review||Overview |
Intel Iris Pro Graphics 5200 Mobile are Integrated Graphics in some of Intel's HQ Haswell Processors.
The Haswell GT3 Core includes support for DirectX 11.1, OpenCL 1.2 and OpenGL 4.0. Additionally, it also offers better Decoding Performance, when compared to its Predecessors.
It equips a GPU Codenamed GT3e which offers 40 Shader Processing Units, 8 TMUs and 2 ROPs. The Central Unit Initially Runs at 200MHz and goes up to 1300MHz, in Turbo Mode.
Unlike the common Integrated Graphics Cards, this one has access to a dedicated frame buffer of 128MB of eDRAM.
The GPU also Shares the System's RAM which varies from laptop to laptop. Typically, the GPU reserves 1GB. Depending on whether or not the system's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit memory interface. The operating memory clock also depends on the at which speed the System's RAM is running and is limited by the highest operating speed that the Processor supports. In this case, it is 800MHz.
It is then obvious the Memory Bandwidth depends on a lot of factors and thus this Graphics Card performance may vary heavily from system to system.
The Most Powerful Variant Offers Performance on level with a dedicated GeForce GT 745M.

We recommend 4GB of RAM for a system with Intel Iris Pro Graphics 5200 Mobile.
GeForce GT 740M is a Middle-Class Mobile Graphics Card based on the first revision of the Kepler Architecture.
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.
It equips a GPU Codenamed GK107-GT-740M which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 810MHz.
The GPU accesses a 2GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and no way benefits the GPU. The Memory Clock Operates at 900MHz.
DirectX 11.0 Support (11.0 Hardware Default) and support for SLI, Kepler Boost, Optimus, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies
With a rated board TDP of 45W, it is suited for average sized laptops.
GeForce GT 740M is essentially a fast GeForce GT 640M.
Gaming benchmarks indicate its Performance is around 3% worse than the older GeForce GT 650M.
We recommend a decent processor (Intel Core i5 Mobile) and 8GB of RAM for a system with GeForce GT 740M.
